Abstract: The experiment was conducted on Inceptisol (Pather series, Vertic Haplustepts) during the year 2009-10 on experimental farm of the Soil Test Crop Response Correlation Project, M.P.K.V Rahuri for evaluation of a scientific basis for calculating the “Nutrient requirement of maize by conjoint use of FYM and chemical fertilizers based on targeted yield approach on Inceptisolâ€. Based on the fertility gradient approach The validity of these equations were tested by conducting nine follow up trials of maize grain on three soil series of Entisol (Viz.Karwali, Rahuri and Akole), three soil series of Inceptisol (Viz. Pather, Beed and Kolyachiwadi) and three soil series of Vertisol (Viz.Targaon, Ambulga and Babulgaon) during Kharif of 2010-11 Post Graduate Farm, Dairy farm and D block, M.P.K.V. Rahuri. The results revealed that the fertilizer application as per yield target 60, 80 and 100 q ha-1 + 10 t ha-1 FYM to maize crop for validation on different soil series of Entisol (viz., Karwali, Rahuri and Akole), Inceptisol (viz., Pather, Beed and Kolyachiwadi) and Vertisol (viz., Targaon, Ambulga and Babulgaon) in respect to residual soil available DTPA micronutrients (Fe, Mn, Cu and Zn) were increased by the fertilizer application as per yield target with 10 t ha-1 FYM. Vertisols and Inceptisols soils contains more DTPA micronutrients. The soil order Inceptisols and Vertisols were higher in total uptake of iron (12.40 and 13.63 kg ha-1), zinc (1.82 and 2.14 kg ha-1), manganese(0.950 and 0.981 kg ha-1) and copper (0.760 and 0.825 kg ha-1) respectively. Soils of Vertisols and Inceptisols soil series were builtup the residual soil fertility in respect to major, secodnary and micronutrients by the addition of 10 t ha-1 FYM with yield target approach of fertilizer application.
